I'm not sure what you mean. Could you elaborate? Do you mean links in the actual video? I'm relatively new to YouTube uploads, so any assistance would be much appreciated.
Once logged in to YouTube, go to "Video Manager" then "edit" there you will see the description. I believe that the individual above was saying that you should include either your personal github link there or any other links that you described in the tutorial so that the user could simply click the link in the description and stay engaged with the video!
P.S. your tutorials are amazing, and thank you for taking the time to complete them!
